LT1881/LT1882 Dual Quad Rail-to-Rail Output, Picoamp Input Precision Amps DESCRIPTION
LT®1881 LT1882 amps bring high accuracy input performance amplifiers with rail-to-rail output swing. Input bias currents capacitive load driving capabilities superior similar LT1884 LT1885 amplifiers, cost slight loss speed. Input offset voltage trimmed less than drift maintains this accuracy over operating temperature range. Input bias currents ultralow 200pA maximum. amplifiers work total power supply voltage between 2.7V (fully specified from ±15V). Output voltage swings within 40mV negative supply 220mV positive supply make these amplifiers good choices voltage single supply operation. Capacitive loads 1000pF driven directly unity-gain follower applications. dual LT1881 LT1881A available with standard pinouts PDIP packages. quad LT1882 14-pin package. higher speed device with similar specifications, LT1884/LT1885.

LT1881/LT1882 APPLICATIONS INFORMATION
LT1881 dual LT1882 quad amps feature exceptional input precision with rail-to-rail output swing. amplifiers similar LT1884 LT1885 devices. LT1881 LT1882 offer superior capacitive load driving capabilities over LT1884 LT1885 voltage gain configurations. Offset voltages trimmed less than input bias currents less than 200pA grade devices. Obtaining beneficial advantage these precision input characteristics depends upon proper applications circuit design board layout. Preserving Input Precision Preserving input voltage accuracy LT1881/LT1882 requires that applications circuit board layout introduce errors comparable greater than offset. Temperature differentials across input connections generate thermocouple voltages 10's microvolts. board layouts should keep connections amplifier's input pins close together away from heat dissipating components. currents across board also generate temperature differentials. extremely input bias currents, 150pA, allow high accuracy maintained with high impedance sources feedback networks. LT1881/LT1882's input bias currents obtained using cancellation circuit on-chip. This causes resulting IBIAS IBIAS- uncorrelated, implied specification being greater than IBIAS user should balance input resistances each input lead, commonly recommended with most amplifiers. impedance either input should kept small possible minimize total circuit error. board layout important insure that leakage currents corrupt IBIAS amplifier. high precision, high impedance circuits, input pins should surrounded guard ring board interconnect, with guard driven same common mode voltage amplifier inputs. Input Common Mode Range LT1881 LT1882 outputs able swing nearly each power supply rail, input stage limited operating between -1V. Exceeding this common mode range will cause gain drop zero; however, phase reversal will occur. Input Protection inverting noninverting input pins LT1881 LT1882 have limited on-chip protection. protection provided prevent damage during handling. input transistors have voltage clamping limiting resistors protect against input differentials 10V. Short transients above this level will also tolerated. input pins sustained differential voltage above 10V, external limiting resistors should used prevent damage amplifier. resistor each input lead will provide protection against differential voltage. Capacitive Loads LT1881 LT1882 drive capacitive loads 1000pF unity-gain. capacitive load driving increases amplifier used higher gain configurations. Capacitive load driving increased decoupling capacitance from output with small resistance.
